About ten minutes had past since Bill had died, Sherlock had placed the body in Mrs Hudson's flat, until he had the time to get him taken to a morgue. Even thinking of morgues made Sherlock ache for his pathologist. Sherlock made his way up to his flat, managing to calm his nerves a fraction, forcing himself to think clearly and rationally about the whole situation. Bill had told him that Molly was being held by Moriarty in a hideout under The Embankment, Sherlock knew that she was undoubtedly in great danger. He began pacing the living room, his hands and legs shaking slightly with a revolting mixture of fear, worry and dread. 'Molly' he kept whispering, apologetically under his breath.'Molly' Suddenly, Sherlock heard the front door open and listened as someone bounded their way up the staircase. A few moments later, Greg Lestrade filled the entrance to the livingroom, panting and staring at him with an expression of panic and anxiety.

"Sherlock" He panted, staring at Sherlock; he had never seen him so terrified in his life. "You alright?"

Sherlock's expression suddenly reciprocated, the fear that was written over his face had now completely distorted, all Lestrade saw now was determination. His mask was back on. Lestrade watched him curiously as quickly turned and grabbed his coat, flinging it over his shoulders and tying his scarf hurriedly.

"She's at The Embankment" Sherlock said, avoiding eye-contact as he glided past Lestrade, running down the stairs.

Sally Donovan glanced in surprise as Sherlock sat into the back seat of the police car, Sherlock Holmes had always insisted on getting a cab rather than hitch a lift, but she knew the circumstances, Greg had explained the situation to her as they made their way to Baker Street and she had to admit; she was concerned. She nodded at him as he caught her gaze in the front mirror, he nodded back. Lestrade hopped in a second later. Sherlock was silent for the first few minutes, staring at his watch and exhaling nervous breaths silently. He now had forty minutes to save Molly Hooper... 'And what if you don't save Molly Hooper...?' The cold voice of question came into his mind, forcing him to imagine what it would be like..being too late; watching The Embankment erupt, filling the London's dark night sky with golden flames ...and not being able to save her.

Sherlock shook the thought out of his head, that would not happen..he would save her, even if that meant that he might not save himself...

"So what's the plan?" Lestrade piped up, shaking Sherlock out of his troubled thoughts. Sally looked back at him expectantly, but with a warmth he had never seen in her before. "Tell us what you need" She said, quietly, sincerely.

"There's a bomb" Sherlock said quietly, watching Sally's face drop, she nodded.

"Where?" She said with a strong voice, picking up the two-way radio that was placed in the dashboard of the car.

"The Embankment..a source, a reliable source has informed me that the bomb is set to go off at twelve am" Sherlock said, watching as Sally repeated the information through the radio.

"Send back up immediately" Sally said through the radio before turing back to Sherlock "And Molly's in there?"

"Yes" Sherlock muttered, only barely concealing the sound of terror in his voice. Sally nodded, her face was tense and her eyes were darting as she tried to put her head around the whole situation.

"And Moriarty is definitely back?"

"Definitely" Sherlock said, losing patience. They were still about five minutes away from The Embankment and although the police siren was allowing them to fly through the thick London traffic with almost no hesitation, Sherlock still felt that they were traveling at a snail's pace.

"Where in The Embankment? There are quite a few buildings there..?"

"I don't know!" Sherlock burst, panic in his ringing voice. "Somewhere underground..secret.."

Sally opened the front glove compartment and took out a fold up map of the city. Sherlock watched as she opened it and traced it with her finger, finding The Embankment after a few moments.

"Alright here it is..Victoria Embankment" She said "Kings College is here..it goes down a bit..for about a mile or so..it ends here.." She said holding up the map "at the Little Brown Book Shop..."

Sherlock sat up rigid before leaping forward and grabbing the map out of Sally's fingers, making her gasp in shock. "Sound familiar?" She said hopefully as Sherlock looked down at the map.

"Let me tell you the story of the.."

"Little Brown Mouse" Sherlock proclaimed, relief flooding his body. He checked his watch, he had half an hour.

"What?" Lestrade asked, confused but hopeful. "I know where she is"

Sherlock couldn't contain a small smile as he watched Lestrade and Sally sigh quietly in relief. As the police car arrived at Bookshop a few minutes later, it was quite an old looking building, with gray, cold stone and long shop looked long out of business, with an old faded sign and a few broken windows. Sherlock stared up at it coldly with a cold sense of foreboding. Sally turned to Sherlock, about to speak;

"I'm going in alone" Sherlock said sternly, still looking up at the building. Sally looked back at him harshly.

"What about the bomb? There could be other people in there Freak. We need to start evacuations.."

Suddenly, as Sally was speaking, there came a humming, static from the previously silent two-way radio, the sound was eerie and rhythmic. They stared at it in confusion for a moment before Sally leant forward and picked it up.

"Hello...Hello. Is anyone trying to make contact?" The static continued as she released the push-to-talk button, but this time it was louder and more malevolent.

"I think its broken" Lestrade said, but was interrupted; "S-Sherlock..." Molly's rasping, terrified voice filled the car;

"Sherlock m-must come i-in alone" Sherlock stared at the two-way radio in horror.

"Molly!" He yelled, pushing himself further into the front of the car. "MOLLY! Don't worry...I'm coming for you..do you hear me? I will save you!" Tears were filling his eyes, but he forced them back. Molly was silent, Sherlock began to panic "Molly!"

The radio went silent once more. The static had stopped and the only sound in the car was Sherlock's petrified panting. After a moment, Sally turned to Sherlock, concern written all over her face.

"Sherlock.." She was shocked that she called him that, not 'Freak' "Are you alrigh-"

But before Sally could finish her sentence the radio buzzed once more, Sherlock sat forward, listening...waiting fearfully for Molly's voice. But he was met by another's;

"Hickory, Dickory Dock"

Moriarty sang quietly, childishly;

"The mouse ran up the clock

The clock strikes twelve..

say your farewell..

Hickory

Dickory

Dock"
